Title: Monostable multivibrator
Inventor: IKEGAMI ICHIROU
IPC: H03K3/0232
Filed: 1980-06-04
Abstract: PURPOSE:To obtain an integrated circuit of monostable multivibrator having a high performance, by comparing the voltage of a charging/discharging circuit with the reference level of a reference voltage generating circuit and resetting a bistable multivibrator when the voltage of the charging/discharging circuit exceeds the reference voltage. CONSTITUTION:When a trigger pulse of VT is applied to a trigger terminal 1, a bistable multivibrator 2 reverses to turn off a switch circuit 3. Thus a charging/ discharging circuit 4 starts charging, and accordingly the charging voltage V3 increases. When the voltage VS becomes higher than the voltage Vref of a reference voltage circuit 6, the output voltage VR is produced from a voltage comparing circuit 5 to reset the vibrator 2. As a result, the circuit 3 is turned on to discharge the charged voltage of the circuit 4. Thus a stable state is obtained. In this case, a monostable multivibrator can be produced with a terminal case, a monostable multivibrator can be produced with a terminal that decides the pulse duration. As a result, an integrated circuit can be obtained for a monostable multivibrator with a high performance.

Abstract: PURPOSE:To provide a method for inexpensively producing a TiAl intermetallic compd. imparted with functions, such as wear resistance and strength, by subjecting a TiAl-based intermetallic compd. to a carburization tr,eatment by gaseous hydrocarbon. CONSTITUTION:After the surface oxidized films of the TiAl-based intermetallic compd. are removed, the compd. is brought into reaction with gaseous hydrocarbon at the condition of >=950 to <=1300 deg.C to allow titanium carbide to be formed by the carbonization reaction from the surface. C3H8 is used as the gaseous hydrocarbon for a carburizing gas. The thickness of the titanium carbide reaction layer is controlled by holding time within a range of >=1 to <=100 hours at the time of the carburization treatment. As a result, the surface of the TiAl- based intermetallic compd. is hardened by carburization and the TiAl-based intermetallic compd. having the excellent wear resistance is inexpensively provided in a large amt. This method is widely applicable even as a surface treatment method for the TiAl-based intermetallic compd.

Title: Analog switch circuit
Inventor: SAITOU TADASHI
IPC: H03K17/687
Filed: 1981-05-20
Abstract: PURPOSE:To obtain excellent high-frequency separating characteristics, by using 5 transistor switches, reducing the stray capacitance, and keeping the gate at sufficiently low impedance at switch-off. CONSTITUTION:When positive and negative voltages are applied respectively to power supply terminals 4 and 5 and a negative signal is applied to a control terminal 3, MOS transistors TRQ1 and Q2 are biased via load resistors R1 and R2 and an analog switch circuit is in on-state. Next, when a 0V signal is applied to the terminal 3, MOSTRs Q3-Q5 are in on-state and the TRsQ1 and Q2 are interrupted. Thus, the TRsQ3 and Q4 are driven at switch-off to keep the gate of the TRsQ1 and Q2 at a low impedance, and the off-isolation characteristics to a high frequency signal can be improved by eliminating the stray capacitance generated between the connecting point of the TRsQ1 and Q2 and a semiconductor substrate through the driving of the TRQ5.
